Amen.
Out of all the programs I use, no program comes close to crashing as often as Live Cycle Designer. It's buggier than a beehive, and I only use it as a last resort. Ours crashes long before we get into the 20-page range. If I'm using it for three hours, I can expect about six crashes. I can run Word, Photoshop, Quark, Excel and a handful of other programs all at the same time, but I can't run Live Cycle Designer all by itself for 30 minutes without a crash. I don't know why, but it's not a memory issue.
