Hi Shenn,
Thanks for reporting this problem.
Are you using the picture button object in the DataWindow?
If yes, please replace the PBDWE190.dll (default directory is: C:\Program Files (x86)\Appeon\Shared\PowerBuilder) with this attached one and see if it works on your side. (see the attachment)
Please back up your old file before replacing it.
After that please restart the compute and see if it works on your side.
If no, I suggest you report this problem to our ticket system: https://www.appeon.com/standardsupport/newbug so it can be properly received and tracked. Please also provide a sample PB test case (with PBT / PBL) when you submit it to the ticket system. Thanks in advance.
Regards,
