Problem - Editing rhtml in NetBeans is very slow - only for me?

Hi

Did anyone except me ever experienced very slow response when editing rhtml in NetBeans? It starts ok, but after a couple of minutes of editing it takes several seconds to move the cursor from one line to another. I'm on Ubuntu and using the today's NetBeans rubyide build. I've tried to switch off all features for the RHTML editor in 'advanced preferences' but it didn't help. Any advice would be appreciated

Thank you Eugene
