Since the release of 4.0b I've noticed more crashes of L4. This only happens on my Win 7 64 bit machine -- (HP Pavilion Elite, 1TB DDR, Core 2 Quad CPU Q9300 @ 2.5 GHz, 8 MB RAM) I have a similar home system in a Dell that's 32-bit but I'm not getting the same problems with it.
The problem first occurred when I received the initial download of 4.0b. The system wouldn't allow the install, claiming I needed administrators rights -- funny since I'm the only user on the computer. So I "installed as administrator". After the install, starting the system caused a crash, I then restarted the program and everything runs well. This occurs daily, every first start is meet with a crash and then a restart. After the restart everything is fine.
Additionally, any updates since, and there have been 2 to my knowledge, have failed and caused me to use the run as administrator option. Anybody else experiencing similar oddities? Any idea of what's happening or causing this?
