Unlike ConQuest, On-Screen TakeOff does not have problems with the Scaling setting of the Windows graphics options, however, if your resolution is too low - such as the 1366x768 of most low-end laptops - then some of the windows will not fit on the screen and you will not be able to click the OK or Cancel buttons.
The only solution for this is to work at a higher resolution. This may be a setting change, it may require you to get a second monitor. If the issue relates to a session on a terminal server, then your IT should be able to force the resolution that the remote session runs at.
TakeOff popups are too large
The OK button cannot be accessed.
