Shortcodes affecting Tweet Blender?

Hi,

An odd problem, I have. I can add two different Tweet Blender tweet lists onto a page, either sequentially or side-by-side on a table (using the form method). But if I use something like posttabs, the shortcode format stops the tweets from appearing.

Let’s say I did:

[tab: One]
form
[tab: Two]
form

Then ‘[tab: Two]’ would cause it to stop working.

Anyone else seen this behaviour, or is it just me?
