Slow file open dialogue

[FloDX]

The file open dialogue in eLamX² (Version 2.7 under Windows 10) was reported to be very slow on some machines. Under so far unknown circumstances, opening and navigating between different folders produces lags between seconds up to a minute.

This issue seems to be related to the NetBeans platform, as e.g., reported under:

• Navigating the file system with netbeans is VERY slow
• Netbeans 15 - Clicking on "Open project..." hangs for long time #4673
• Netbeans Add/Open File/Folder Dialog becoming slow
