Hello Linda,

it looks like something is messed up with the fonts on your PC. Maybe the font, which VIP uses in the editor, is missing.

Under "Tools", "Options..." it is possible to specify font for all IDE windows.

I suppose my font settings are default:

Try to change the fonts in the Options box to ones which are correctly installed on your PC. Most common windows fonts are Arial and Courier New.

Another -maybe better- idea is, to restore the windows fonts on your PC. Many sites are explaining, how to do it. On a quick search I found site How to Restore Default Fonts in Windows 10 and 11?

In old VIP 7.3 dialogs have been looking different, but fonts have also been selectable:

I can vaguely recall that problem, but not what caused it nor what removed it. I do however know that it doesn't exist in newer versions and that Vip 7.3 is very old. I think you should upgrade.
