I encountered this strange behavior on the log page - bug or feature ?

When I press long on a QSO and select "Edit QSO" in the pop-up menu, the QSO window pops up but you cannot change any QSO content, you can only choose "Save QSO" or "Set Details".
When I duoble-click on a QSO the (same) QSO-window pops up and you can select "Edit" at the bottom and everythig works fine.
