While updating a sequence today I had been working on for a day, I applied the strobe effect to my Main Display all group. I had the strobe effect up to about 140 lights. It was working and was showing teh desired effect in teh model preview window. So I decided to render the sequence to play it so I could see the newly added effect. After about an hour of sitting which is unusual for my machine and sequences, xLights popped up an out of memory error. I had only mail open at the time. I had to force quit xLights and reboot the machine. Now with nothing but xLights open, I decided to simply delete the strobe effect on the Main Display group. At that point it simply became non responsive requiring a hard boot. This occurred every subsequent attempt to restart and delete the offending effect. I then upgraded to .35 and it did the exact same thing requiring me to fall back to an easier version of the sequence. I have not tried adding it back again. Attached are the log files for one of teh attempted deletions and crashes. I did not catch the original one which had teh memory leak as it would not allow me to do anything in xLights. Also attached is the affected sequence.
