Add Symbol Box popping up

[Avatar12]

I have a quirky situation which  may be a bug in another program in my computer causing this issue.  Numerous times during the day the Add Symbol Box pops up on my  workspace, and then continuous dotted lines run across  the inside of the box.  I can close it by typing in a symbol. 

 

I mostly use this computer for  looking at charts during market hours  and not much else.

 

Thanks

In MT, to add a symbol, you simply start typing it. Somehow one of your keyboard keys thinks it is getting pressed (and stuck).
