IDE Freezes after opening filedialog or commondialog

Hi,

I've some trouble with the Arduino IDE in windows 10. (the problem is existing in several IDE versions) everytime after a update i hope it's fixed :)

after using the open or save dialog (CRTL-O / CRTL-S) and cancelling it, the IDE freezes. or closing a project with CRTL-W and than hitting cancel the IDE freezes and can only be closed by ending the task. (very annoying when you haven't saved the probject :( )

I'm running Windows 10 (updated to the last version) with IDE v 1.8.12 >> i've the same problem at both of my pc's. the version of java i'm using java version "1.8.0_231" Java(TM) SE Runtime Environment (build 1.8.0_231-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

is this a known problem, and is there a solution?

I hope someone can help.

Reinald.
