SWG going back to character select screen : Star Wars Galaxies Discussions

I have a character that can sample resources without resting. I use Xunleashed to click where the sampling popups come up.
Problem is that after awhile SWG dumps me back to the character select screen. I am running Win 2K Pro. I make sure my afk timeout is off. I have used combinations of mouse clicks along with keyboard commands to try to keep the SWG client active. I have also used a short in game macro script that samples for 600 seconds then sits me down for 25 seconds then repeats. If I add an "Enter" key to the recorded macro it will actually click the the next button for me and put me back in the game but the alt key is not pressed so the macro starts moving where I am looking.
The weirdest thing is that occasionally it will work and not time out after like 18 hours. I have also tried rebooting and reloading Xunleashed to make sure everything is cleared from memory. Has anyone seen this or have any ideas? (BTW the client does not time out if I just run an in game macro to sample all day and let the poppups come up)
Thanks for any help in advance.
