I recently upgraded bad behaviour (from 2.0.23 to 2.0.24) on my blog, and found I couldn’t activate the new plugin (I got a http 403 error).

Reverting back to V 2.0.23, and everything was fine again.

At first, I thought it was a bug with bad behavior, but when I tried updating from firefox, bad behavior activated normally.

I went back to Maxthon (ie7), and found I was being blocked from my blog (error 403 again).

OK, looks like an IE7 problem.

I tried from another PC, and I could access computer-aid.com.au/blog without a problem

OK, the problem is with IE7, but only on my main PC.

I tried running IE7 in safe mode, but the problem persisted.

I tried uninstalling ie7, then reinstalling it. But that didn’t fix things.

I used winmerge, so I could see what had changed between bad behavior 2.0.34 and 2.0.24.

The only obvious difference was a check for the string “User-agent: “.

I commented out that check within BB, and IE7 was working again… but this is just a work-around. I want to know the reason for this problem.

I found a nice site called: http://whatsmyuseragent.com/

And I find my user agent was: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; User-agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; http://bsalsa.com) ; MAXTHON 2.0)

Ok, some duplication, and a suspicious entry for bsalsa.com

A quick web search gets me a solution, but not much more.

I start regedit, go to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\User Agent\Post Platform

and then delete the badly formed user agent value (there was only one value).

I restart maxthon (ie7), reinstall BB 2.0.24, and I can finally work on my blog again.

Please: I don’t want any comments about browser X is better than maxthon. I like maxthon. I’ve been using it for many many years, and I’m happy with it.

I also use ie7, firefox, opera, safari, chrome… but maxthon does just what I want.
