Hi Van,
I am afraid that for some reason the IDE height and width have become greater than the screen height and width, so the Object Properties and Project Explorer are visible but they are just “out of the screen view” and that is why the Properties menu item is disabled when you select an object (this menu item is only enabled when the Object Properties is hidden).
Please close any instance of EC, open your EasyCode.ini file (or any other custom “.ini” file you have created), search for the MainHeight, MainLeft, MainTop and MainWidth entries and left them empty like that:
MainHeight=
MainLeft=
MainTop=
MainWidth=
This will make the left, top, height and width to get their default values. Now save the “.ini” file and run EasyCode.exe.
Regards,
Ramon
