Hello everyone
I have slowdown problems with opening dddw
Ecosystem:
windows11
pb2022r3 (build 3391), but I have the same problem with pb2019r3
pfc

If I open many windows (windows with many fields and dddw) when I click on the dddw to open them, they open late. The positioning on the field happens immediately, but then there is a significant wait before the list of dddw values ​​is displayed. (I have gotten to have waits of 3 seconds).
It seems that if open windows increase (complex windows: many fields, many dddw, many tabpages) the response time of opening the dddw increases proportionally.
You understand that in an MDI application it is not nice to limit the opening of windows and this causes strong slowdowns.

I'll start by saying that
•⁠ ⁠RAM is not in crisis
•⁠ PROCESSOR is not in crisis
•⁠ ⁠I checked with debug and the only event that fires is the click and it has no code that can interfere. I even deleted all the code to make sure there were no recursive ones that cause problems.
•⁠ ⁠dddw are loaded when the window is opened and not when it is clicked.

 

thanks in advance for your reply
