If the "mail checker" icon on the panel is used, but no command is specified,
the icon still "pressable" - it would be nice if the icon would not be
"pressable" if no command was entered.
Steps to Reproduce:
Making the button insensitive also prevents the use of the right-click menu , so
I don't think that is possible.
If I don't think of some clever way to do this, I will probably close this report.
Setting the severity to enhancement.
Ok, setting this to WONTFIX. Work is underway for a new mailwatch plugin.
