Hello

I'm not sure if this is a bug or not but it looks strange to me.

I use PowerClient for deploying my application.

What's going on:

If I start the application from the generated desktop link then it works fine. The link targets this:

C:\ProgramData\Eclipse\PBApps\Applications\optima_optima-test\Optima-Test.exe

 

Next I add a parameter to the link:

C:\ProgramData\Eclipse\PBApps\Applications\optima_optima-test\Optima-Test.exe "param1"

The application starts with parameter 'param'. This is  still OK.

Then I remove the parameter

C:\ProgramData\Eclipse\PBApps\Applications\optima_optima-test\Optima-Test.exe

What I'd expect was the app starting with no parameter.

But the app started with parameter "param1" again. The reason is startParam row in pbapp.ini which always contains the last used parameter regardless the parameter has been deleted. The workaround is simple - Using a weblink or just add a random parameter to .lnk works. But the behavior is strange. Plus there's a bonus there: If I use a question mark as a parameter in the .lnk file then pbapp.ini multiplies these '?' and never deletes them. The questionmarks queue only grows. This is my current startparam row:

startParam=-multi "https://optima/optima-test/?????"
