[SD-User] Jumping cursor

[summers brian]

For some time now I've been plagued with what I can best describe as a 'jumping cursor'.

What happens is that in S&P mode the cursor will suddenly jump to the 'My Call' part of the screen which means that callsigns cannot be entered. Pressing the minus key returns the cursor to the correct place although there have been times when after pressing the minus key the cursor immediately jumps back to the My Call area. Because this is S&P mode I'm not transmitting so it's not an RFI issue.

Thinking it might be link related I've tried disabling the link and even disconnecting the serial cable to the rig but this has not had any affect. I've also recently changed from an old P1 with Win98SE to a P4 with XP Pro  and still have the same problem. And having used several versions of SD it's not version related.

I only operate CW contests for the most part so I cannot comment on SSB operation.

Can anyone help me with this one please?
