When creating a new message or opening an existing message results in the compose dialogue being loaded with its co-ordinates outside the confines of the screen; ergo not visible.
To resolve this problem, the registry entry that controls the position of the compose dialogue can be manually edited to a location inside the screen.
Open the registry editor by clicking Start >> Run, and type regedit. Click OK.
Navigate to the
Double click on the top REG_DWORD value and set its data to 1
Double click on the left REG_DWORD value and set its data to 1
The next time the message compose dialogue is loaded it will position itself in the top left corner of the screen; any position to which you move the window will be saved when the window is closed.
