vBulletin text entry box issue (scrolling on phone)

I know I’m not going to be able to describe this properly, but maybe someone has the same issue and can help out. So you know what I’m working with. I’m using an LG Optimus running Froyo (2.2). This happens whether I connect using the stock browser, Dolphin, Opera Mini or Skyfire, so it isn’t the browser. And it happens whether the Swype keyboard is present or hidden.

Everything is fine until the cursor gets to the bottom of the window. If I breath only through my left eyelid while fondling a pregnant yak I can manage to continue my witty posts without incident. However, if I blink or the yak farts, the text will scroll up a couple lines and all that wisdom gets buried. I’ve tried “holding” outside the box to scroll the text. No dice. I’ve tried rotating the screen. I tried to preview then edit. Nothing. And every failed effort just pisses the yak off more since my stress management system is to punch the nearest yak. You can see why this has become such an issue. It happens on other vB sites so I know it’s something with the software if not the phone. I went to their site forum but it looks like that’s aimed only at their customers. But I figure with the brainpower here this might actually be a better place to find help.

So how about it? Anyone know what I can do? Thanks.
