Wierd problem with Hauppauge remote and left button

Hey folks - kind of a weird one.
I have my USB UIRT working fine with Girder and my Sage client - I went through and "learned" the settings via Girder and all the keys workd dandy across the boards except when I press the left arrow key, the UIRT box indicator light goes solid and it stops accepting input for about 8 to 10 seconds, then the light goes out and I can proceed. The left arrow button doesn't take action.
I've learned and relearned the left button but this conintues to happen - very weird. I doesn't affect any other key on the remote and I've tried two of the same type of remotes (came with the 250s I bought).
Any idea of what this can be or how I troubleshoot this?
thanks much.
