vixen may seem cursed but let's look a little deeper. How much memory does the show PC have.
what timing is set in the sequence.
although you can edit the sequence flatten it, remove add modify a profile it likely isn't that. In fact with testing this found no difference in ,making those changes. there is a change that will definitely impact the PC running.
Here is what I found.
I had a machine with 3 meg of ram on it winxp with the latest updates and virus stuff. one night no problem another nothing but headaches. So I didn't change the profile, I didn't change the show, and didn't change the schedule so it has to be something else. It has to be windows.
and it was as windows hums along nicely with nothing running auto stuff starts amdmost often doesn't stop correctly
here is what I did, I got a machine with 4meg I know that winxp can't use 4 meg .. so be it, but a machine with 3 meg had a little less memory. I Know it is a memory issue I am dealing with now.
then I uninstalled everything that I didn't need for the show PC leaving basically some antivirus software and Vixen.
No more issues except when windows starts it auto crap, way too technical for here. so every once in a while (couple of days) I go in using task manager to turn off stuff that doesn't need to be running.
I run 50 songs in the program and it is 137 minutes long. Each sequence has been edited to use the biggest time slice 100. I bet you could use a bigger time slice setting but this works for me. I use one profile only.
It really is the size of the sequence file.
to see the difference set the time setting to say 10 and save the sequence you will see that at the setting the Sequence file is 4 to 6 times larger then when the setting is at 100 or larger
I edit and sequence with a finer time slice and when I am done I just set the time slice (event period length) to 100
problem solved
