First of all: really usefull and nice program!
You are using the font "MS Sans Serif" in almost every of your ScreenCaptor windows/dialog boxes.
The big drawback of this font: it's a bitmap font, which cannot be enhanced by Windows XP's ClearType feature, thus giving a pixeled look on modern flatscreens, when ClearType is enabled.
Please consider using the Microsoft default font "MS Shell Dlg" instead. This automatically resolves to "Tahoma" on modern Windows systems or "MS Sans Serif" on old Windows systems. This preserves compatibility while giving a nice and smooth look on modern cleartyped flatscreen systems.
