Hi
VP 6.30
Agreed..It's a bug but it's not intermittent.....,
In the Text Editor, If Ctrl key has been pressed but then released (i.e. presumably now having no action) the Register Software window comes up when R is typed. After that it seems to come up each time R is pressed (r seems OK). If the window is then closed cursor is at start of text again. The effect is removed if Ctrl is pressed again. The edit window obviously responds to the Ctrl key being pressed and released as the thumbnails are regenerated when it is pressed.
The Register software window is the bottom choice in the list under the green Menu key In my version of VP6.30
So until it's fixed don't press the Ctrl key when entering text. If you do then press it again. It's easy to touch this key when you want Shift instead.....but doing it again is the cure.😉
