Slick-C Stack Error when Slickedit gets focus

[pmsteinm]

I'm on Windows 10 1903 starting with Slickedit 21.0.2 I will get a stack error a few times a day when Slickedit gets focus (I have Windows set to do focus follows mouse and no auto-raise):

 Invalid object handle
mouse.ex 24582 _MouseMoveTimerCallback(557)   p_window_id: 5   p_object: OI_FORM   p_name:

I have hotfix 2 applied.

Get hot fix 3 when it is available (soon).

So far I have not had this problem occur with hotfix 3.

Ha, I spoke too soon. It just happened with the same values listed above. A different program had focus and when I moved my mouse back to Slickedit the error occurred. I can't get it happen on purpose though or say what specific sequence causes the problem.

Did you mean 21.0.2 in your original post?  Or 23.0.2 ?

If you got exactly the same values, the file offset, you should double-click your help > about to see if you really have the hot fix applied.  With the fix applied, I would expect the stack to occur in a different location within mouse.e.

Yes I did mean 23.0.2.  I have hotfix 3 loaded. Next time it occurs I'll check the addresses again to be sure. Either way this problem is less common then before.

The stack occurred again, and the line number is different as expected:

 Invalid object handle
mouse.ex 24582 _MouseMoveTimerCallback(614)   p_window_id: 5   p_object: OI_FORM   p_name:

I'm pretty sure this time it occurred when another program had focus, a windows 10 notification popped up, and I gave Slickedit focus.

I was not able to reproduce your problem, but I am checking in an additional safety check to guard against this.  The fix will be in the next hot fix (if there is another for 23.0.2).  It will also be in the next beta build for SlickEdit 2019 (v24).
