ledtriks scrambles

[biffklg]

I am wondering if anyone else is having this problem with ledtiks and what it might be. I leave my computer on all the time and very rarely turn it off, this is what I get:

I run vixen and run a sequence for a while, usually a couple hours.
After the couple hour run I then stop the sequence and shut down vixen.
I leave the computer on and go to bed for the night and then the next evening I run vixen again and run the same sequence.
Without doing anything I will check the display and the screen is almost unreadable. There is like 3 rows of led's behind the letters that just fire randomly.
If I shut off everything and then restart my computer and try again it works just fine.

Just curious if anyone else has this problem and what might be causing it..
Thanks

After you shut down vixen for the night check
the task manager make shure vixen shuts down

Are any of the input pins left floating on the LedTriks board? (I don't have the schematic and datasheets in front of me.)

This could be difficult to troubleshoot; if bad data really is being sent out the parallel port, I don't see how we could capture that without a logic analyzer.

I have checked that and yes it does shut down, or at least doesnt show in the task manager.

As for the other question, I don't even know what a floating pin is. I soldered them all to the board though.

I figured out the problem. I had the ledtriks board on all the time as well and somehow it gets messed up just sitting around. If I turn it off for a bit and then back on and run vixen it is fine... Go figure..

mine did that and I tried another computor and it worked on that one fine something in the lpt1 port is bad on the other one..It might of been when I sorted the leads......oh well I thought I would suggest making sure it wasnt just the port..
