mouse cursor, up/down works but not left/right

[lost lemming]

I've tried different mouses it's not the mouse.
Sometimes if I just leave the mouse there, it will jump around on the horizontal axis at random times.
Any idea?
I damaged a track a while ago when fitting in my ESC scan doubler (which is fixed now with a jumpwire) I think it supplied 5v to the clock TTL chip below the denise. The clock ttl chip was essential for the multiplexer TTL chip to work. Do you think it's something to do with that?

Does anyone know if it's possible to move the cursor around with the keyboard? I know you could do that with an ST holding alt and using the arrow pad. I very quickly need to do a change on workbench but the mouse is stopping me

also, after about 10 minutes of the amiga warming up, the mouse will eventually move ok. This it just really odd!

I had this problem on an a3000 awhile back. Had battery damage and really screwed up DIP sockets. REmoving the sockets and soldering the denise directly to the board cleared it up. I think that's what I did.

Definitely sounds like a trace, I had the same problem with my A1200 after an unsuccessful keyboard hack, although it was the keys that didn't work.

here are two links about what I did.

"When i soldered denise to the board, i knicked a line under the chip when removing the socket. It looked real minor, so i didnt bother to check up on it. Turns out that was a mistake, as video and everything else with the system is top notch, i only get horizontal mouse movement. A quck check with the probe reveals that no vert signal is going to the chip, so here is my fix for that, everything is working great now."

Odd, I swear I had the problem *before* I did the repair. Maybe not.

It sounds like a cold solder joint. I recommend that you have someone redo the joints with a low wattage Solder Iron (25W).
