The issue occurs in my windows-OS, using the [latest] version (3.2.32000) of ganttproject.
When I go to:
File → Import → Spreadsheet → Browse
or
File → Export → Spreadsheet → Browse
The application stall for some seconds. (This is true regardless the Spreadsheet or other option)
Then a window open to select the file I want, or the location I want to save.
But every interaction with this window is very slow. For every click I have to wait a few seconds. It’s really annoying!
Can these “stalls” be fixed somehow?
