PlayBook has problem with Yahoo and Flickr

Just wondering if other PlayBook users encounter problems like Yahoo pages closing or it takes along time for pages to develope with lots of checkerboard time. Tonight I was trying to checkout some photos on Flickr but it closed back to the browser or had a double image of the Flickr homepage. One last thing does your PlayBook leave a period when you hit the space bar sometimes. I type up simple invoices and estimates using Docs to Go and this stray period keeps happening. I have been considering a total wipe but that is pretty radical.
Thanks

Clear the cache (hit the clear all option) and reboot the device, should help with the crashes.

There isn't much that can be done about slowness. A wipe every now and then also helps, but after some time, it starts to crawl.
