Dialog box problem - could be my problem only

[tiera3]

Often (feels like about half the time, but I haven't taken notes to determine frequency) I an unable to type more than one character is a dialog box. (The character typed is highlighted, and each time I type another character it overwrites the previous one and highlights the new one.)

Workaround - I type the needed text in notepad and copy, then paste into the dialog box - this works fine.

I know that intermittent problems are the hardest to diagnose, but I just thought I would mention it in case: a) Someone knows of the cause and/or a simple solution, or b) Others are having the same issue.
