Hi Benjamin;

   Thank you for opening a Support Ticket on this issue. I was able to reproduce magnifier issues with my own applications as well as yours. While they did not crash when the magnifier was on - the app did not behave at all properly. Like their keyboard, mouse & Windows messages / message queue were being hampered with when the magnifier was active.

  After turning the magnifier off - the same hampered behaviour continued. However, after closing the PB App and then restarting with the magnifier feature off, the PB Apps returned to normal behaviour.

  The that reason my PB Apps might not have crashed could be because I might be using a newer O/S build than you. I am on MS-Windows W10 build 18362.

Regards ... Chris

Wow, thank you Miguel!

I hope someone from Appeon will take care of this now. Or should I open a support case?

Here's a log PML file generated with Process Monitor v3.20 (https://docs.microsoft.com/en-gb/sysinternals/)

See attached in zipped format.

Here's the .Wer file attached.

Good news (for reporting it to Appeon or Microsoft):

I've been able to kind of reproduce the problem several times on my PC, as you can see here (from application log event vierwer). I can't really pin down when it happens but it seems to have something to do with clicking in the title bar

The way to reproduce it:

0) set my display settings of windows to be 125 % scaling instead of 100%. Not sure, because after setting it back to 100% I could still reproduce the problem.

1) open winglass.exe

2) open magnifier by using windowsKey and type magnifier, then click on the app to open it

3) Click once in the title bar of winglass window, while magnifier in full screen and some magnification +500 for example.

4) Click in the title of the floating magnifier windows toolbar. The winglass application closes down ....

5) then check eventviewer logs:

I also checked the PATH folders. All fine.

Even if we prepare the environment via a VBS script, it behaves differently.

What can't be is that a 32-bit application calls a 64-bit DLL (.\Windows\System32).

By the way, the PowerBuilder IDE also crashes when working with the Windows magnifier and the Datawindow painter. I've worked in this way before to place objects pixel by pixel. And there have never been any problems so far.

So we think that it is primarily a problem with the Windows magnifier, which may be triggered by the PowerBuilder runtime (Datawindow SetItemFocus) or at least conflicts with it. Especially the Datawindow runtime, because windows without a Datawindow control don't crash.

Unfortunately we still don't have a solution except to turn off the options in the Windows magnifier.

Thank you for your ideas so far.

Ok, so there's more than one runtime on the computers.

The pb program is the same, the OS is the same, so in my opinion there's only one possible difference:

- maybe the path, can you compare the path of a pc on which the program works with the path of a pc where the program crashes? Set the path to the correct runtime to be the first bit of the path and test again.

I wouldn't know what else to suggest, sorry.

@Miguel:

We have more than one PB-runtime on our developer computers.

It doesn't work for me, but it works for my colleague without any problems.

Same Windows 10 Pro 1903 with current updates. Same manufacturer.

Older Windows Versions 7 / 8.1 do not have the problem.

I would rather not rename the DLL, because it belongs to the core DLLs of Windows.

@Chris:

The PBACC170.dll is deployed but we have never had to register the OLEACC.DLL before.

Furthermore, the DLL is correctly registered. I checked that.

Hi Benjamin;

    One possible reason ... then OLEACC DLL may not be registered on the odd PC where this is happening.  Have you tried running .... regsrv32 oleacc.dll  ?

Also, make sure that the PBACC170.dll is deployed as well to those PC's where your App is running.

HTH
Regards ... Chris

Could it be that there's more than one PB run-time on the failing computers?

What happens if you temporarily rename the  "OLEACC.DLL" in the windows system32 folder?

HIH

Hi Miguel,

there is no touch-screen. Which option do you mean exactly?

Just a wild hunch: Is touch-screen active?
