as to the flash plugin being disabled, we've had the same discussion on the WeBot fourms and one member found this infomation thqat may be what is happening to Benz145:

"My browser plugins also get turned off every now and then on my N800 running OS2008. I think the browser disables the plugins when the device runs low on RAM memory.

E.g. viewing the flash-based (and memory-extensive?) http://www.flashearth.com on the tablet and navigating around results in that the flash plug-in gets disabled after some time."
