Hey guys,
It seems that for a while now popup buttons have had an issue in Gorm (about 8 months or so). The individual NSMenuItem target/action should be set to the NSPopUpButtonCell and _popUpItemAction: respectively.
While it would be possible to add code to gui to correct this automatically, that is a kludge with very little positive effect. If you have .gorm files where the individual items will not enable, this is probably the issue.
Please recreate these popups, if demand is great I will make a fix to Gorm to correct this issue.
Thank, GC
