The folks over at Opera Mobile have updated the beta release of version 9.5 of their mobile browser.

Addressed is a bug that turned off notification sounds. And while Opera acknowledges that there are other bugs it's working on, they're not fixed in this release.

We have updated the beta1 with a fix for the (very annoying) bug that turned off the notification sounds. The notification bugfix was relatively trivial and had a low risk. We are aware of the other bugs and issues, but these aren't addressed in this update.

Also noted on Opera's blog is our how-to on moving the cache file off your device and on to your storage card. (Commence horn tootage!)

Keyboard problems persist: Aside from the "Out of Memory" errors, one of the other biggest gripes with the 9.5 beta has been with soft keyboards. Opera is aware of this and says the problem lies not with its software - or Windows Mobile for that matter - but with customized keyboards.

Opera supports the SIP architecture and the IME architecture, so Opera works fine with the default Microsoft keyboards. Unfortunately, many new devices have shiny keyboards that look nice, but do not comply to Microsoft's SIP [software-based input panel] and/or IME [input method editor] standard. Those keyboards work well on an edit control, but not with other applications that want to use user-input from a keyboard.

Basically, there are standards with which Opera Mobile works just fine, but some of these newfangled software keyboards just aren't playing nicely. Opera says it will work to make its browser more compatible with nonstandard keyboards, but that there are limits, which makes sense. Standards are set for a reason. Let's hope the keyboard programmers fix things on their end.

Get the Opera Mobile 9.5 beta 1 here, and let us know in the comments if your notification problems are fixed.
