In the Ironfist Editor (editor.exe), when the "Edit Town" window is opened (modified grey window with "graphic style of Windows"), the mouse cursor disappears from the window (you cannot visualise where is the cursor).
This happens both in fullscreen mode and in windowed mode.
Edit:
Precisions.
If you set the Mouse Cursor to "Off" in the System Options, the mouse cursor is displayed.
Also, the "Troops" "Custom" "Mon 1, Mon 2, Mon 3, Mon 4, Mon 5" selectors are full of "?????????????????????????????????????".
And, for "Buildings "Mage Guild", the selector has also "????????"
And, some texts are also replaced by "????" for the buildings (same place as Thieves Guild, Right Turret, etc.).
