Try using the m.gmail.com
The nook color works best on mobile sites. You can put an M in place of WWW for most sites. ie... m.facebook.com, m.yahoo.com, m.gmail.com you get the idea.
The curser problem is not a Nook issue. I have the same problem on 2 dif PC's It is intermittent yet very annoying.
Well the cursor issue does not seem to be intermittent on the nook it's all the time and yes very annoying. Oh, well.
I find it a bit sad that I have to resort to mobile sites with the nook browser. My HTC Evo handles full versions of websites beautifully and it's a phone.
That being said I did purchase this to read books on and for that purpose it works splendidly and so these issues are not deal breakers for me and the nook color. Perhaps these issues will be addressed in a future update.
We are aware of the issue and are working on it. As a workaround:
Facebook: try http://touch.facebook.com
Hotmail: try http://mobile.live.com/hm
B&N Forums: Click on the "HTML" tab when entering text. It should let you type in.
We're working on the issue of not being able to type in certain text entry fields.
NOOKcolor also supports the mobile YouTube site (http://m.youtube.com), which runs on HTML.
