PowerBuilder 2019 GA 2082.

One of our devs discovered that on a particular DataWindow, using the scroll wheel can cause the application to just disappear. I tried it in the IDE and nothing happens. In the exe, the mouse shows busy for a second or two and then it just disappears with no message.

Is this a know bug?

Can u check the detail band height of the concerned datawindow?  We had the same issues for datawindows with zero detail band height.

If the dw has a title, see what happens if it hasn't. Can you post a sample?

Hi Roland;

   FWIW: I never have any mouse scrolling issues on any of my framework apps (ever) using the mouse wheel. It does not matter what the style is of the DWO. If the DWO dataum is beyond the DW Control's size, then scrolling with the mouse, keyboard or wheel is always OK for me.

  My suggestion is to investigate the DC is question and have a look for code on a User Event mapped to a low level O/S message ID or code on the infamous "Other" event that could be causing the crash. Make sure too that you check all the ancestor code on any of these as well. Especially, if they cause other related DC event to fire or make O/S API calls.

HTH

Regards ... Chris
