Turns out it was a corrupted checkbox on the form.... sigh...

Went in and deleted it, created a new one, used this code in the Click...

IF this.Value = .T.
	Thisform.pgf1.page1.txtlimitedby.Enabled = .T.
	Thisform.pgf1.page1.lbllimiteddays.Enabled = .T.
ELSE
	Thisform.pgf1.page1.txtlimitedby.Enabled = .F.
	Thisform.pgf1.page1.lbllimiteddays.Enabled = .F.
ENDIF 

And all is well again! Mouse and Spacebar both work as they should....

Thanks!
