Hi All,
I had previously had this problem ( Gramps 5.2.2 Portable and Forms Gramplet) and after backing up my databases, reformatting the stick, re installing all was back to working.
Now back to the problem even with another stick and fresh install. I have worked on a database in the portable version on a Windows 10 machine for a few weeks. At a different location and plugged into a Windows 11 machine and the Forms Gramplet will not open 
The citations list shows at the bottom but whenever I click on one nothing happens, and this is on three different Windows 11 machines but as soon as I plug the stick back into the Windows 10 machine everything opens as expected?
Has anyone else had this problem or any suggestions as to what might be going on?
