Iaxrpt client transmits with CTRL key

Sometimes I have the PC client iaxrpt running in the background while working on my laptop. When I hit CTRL to do something in the application I am using, iaxrpt transmits for the time the CTRL key is pressed.

I can’t seem to figure out under what scenarios it does this or how to disable it, having looked through the menus.

Any ideas?

Thx. Adrian VE7NZ

That is normal operation for IAXRPT. That is the PTT button. You can use the space bar to toggle PTT or use the CTRL key as momentary PTT.

Thx. Strange though that it does it when I am editing a Word doc or other task in another Window.
