1.9.2 causes weird errors in firefox + chrome

Browserplus was working perfectly for me until the 1.9.2 update today.

Tested this bug on 2 machines running windows 7 64bit
Tested this bug on 1 machine running windows XP 32bit

Had no issues with the previous 2.9.1 version whatsoever!


Firefox (3.6.6):
- dragging files into drop area: get an error "Security error" code: "1000"

- single dropped file is recognised (with error mentioned above) but multiple dragged files are not, when multiple files are dragged only the first file is recognised

- drag drop hover is not firing


Chrome (5.0.375.99)
- dragging a file into drop area I get an error "Uncaught uri/files size mismatch, aborting drop"

This is a complete show stopper for me and my clients. Anyone else having this issue, is there any way to stop browserplus updating and force teh use of a particular version number?
