Are you saying that we need to add the following for EVERY datawidnow on the window when the window closes????????
      Dw_1.Reset()
      Dw_1.DataObject = “”

Why?

For better performance you could also include

[Datastore Behavior]
UseHwnd=0

"NativePDF_Valid=1" was only supported from PB2017 xx until PB 2019 R1 , so you might want to leave that out, depending on which version of PB you are using.

Have a read on UseHwnd=0 on https://www.pb.miguell.work/pb-ini/list-entries 
If  you decide to use it, it negatively affects the print of datastores when you want to user print(true, true) and thus have a Printsetup dialog show automatically (see https://community.appeon.com/index.php/qna/q-a/need-for-documentation-on-all-existing-pb-ini-entries )

BTW: I already reported having to set "accessability=0", to be a problem on the support site: https://www.appeon.com/standardsupport/track/view?id=7798

I only have the below two options in my pb.ini file

[Data Window]
NativePDF_Valid=1
Accessibility=0

 

 

 

The pb.ini from development has all the ones below. Are there ones I should have that could improve the performance of my runtime application?

also, even if this does 'fix' your slowness, you should report this as a bug. Some of the capabilities of having ACCESSIBILITY turned on would be really nice to take advantage of if it gets fixed. I'm also not sure if BOTH the new and old versions cause the slowness or only the one. I took the "nuclear option" and turned it completely off in my application. this is what PB help says Accessibility option in the PB.INI file: Accessibility=0: Disable both MSAA and Microsoft UI Automation Accessibility=1: Enable both Accessibility=2: Enable Microsoft UI Automation only Accessibility=3: Enable MSAA only It is recommended that you enable (value is 1) or disable (value is 0) both technologies; if you set the value to 2 or 3 (enable only one of them), some testing tools may not work well with only UIA or MSAA, and may cause the application to malfunction or crash.

have you turned off ACCESSIBILITY in your runtime pb.ini?  

 

add a pb.ini file to your runtime install directory of the application.

Include the following:

[Data Window]
ACCESSIBILITY=0
