Question: Open dialogue stops working. Unable to select file. Must type file name

This is a very serious problem. Maple 2024.2 on windows 10.

I noticed, may be starting 2-3 weeks now, that sometimes when I do File->Open , and the Open dialogue opens, I am not able to use the mouse to select the .mw file I want to open. 

Can not even close the dialogue by clicking X. Even clickiing on cancel does nothing.  Basically the mouse seems not doing anything.

Only way is to type using the keyboard the file name. Eveything else does not work.

Not only that, the mouse is trapped in the dialogue.

I can't even get it out of Maple to go to another application. AT first, I had to do CTRL-ALT-DEL to get out and use the task manager to kill Maple. Then later I found if I type the file name I can get out.

Here is a movie.  

I do not understand what is causing this. This only happens in Maple for me. Neven seen anything like this before.

Any suggestions what to look for?

I just remembered. 2-3 weeks ago, I closed the left panel. As you see above.

I just tried now, and expanded it again, and guess what, the mouse seems to be working now!

Can someone conform this?  Here is a movie with the panel expanded again:

You see, the mouse now works and can select files.

When I minimize the left panel, the mouse sometimes stops working in file dialogue.

Here is another movie showing this problem much more clearly.

When closing the left panel, the open file dialogue stops working (mouse not working), and when expanding it again, it starts to work!

This can not be a feature right? it must be a bug in the Java interface?
