I have a deployed version of powerbuilder 2021 build 1288 and when accessing a calendar dropdown the application crashes with this error.
I have these two functions in my code which call the user32.dll which is directly where the error message is pointing to. I have a copy of user32.dll in my deployed workspace and for some reason the error is still occurring - other .dlls seem to be working fine.
FUNCTION ulong win_GetFocus() ALIAS FOR "GetFocus" LIBRARY "user32.dll"
FUNCTION ulong win_GetClassName(ulong hwnhttps://i.stack.imgur.com/7PmNS.pngd, ref string cname, int buf) ALIAS FOR "GetClassNameW" LIBRARY "user32.dll"
