Can't drag and drop any pieces

Hi there, I’m having an issue where I cant drag and drop pieces, if I begin dragging a piece it will deselect it immediately meaning I cant move it at all. Im using the latest version of Vassal but I also tried the last 3 versions. This is happening on both the VASL and Vassal40k Modules. I have also reinstalled the latest version of Java. Any help would be appreciated.

There is a known issue where the drag ghosting doesn’t display when you drag a unit that makes it look like you can’t move the unit. In File → Preferences → General Tab try turning on the ‘Drag ghost bug correction?’ option, restart Vassal and see if that helps.

Hi there,
Are using a MAC by any chance ?
