I'm not sure how thorough the testing is!

[brucet]

Each public release of Sellerdeck Desktop gets a minimum of 6 man-weeks (or person-weeks?) of testing, which includes a systematic end-to-end test, and individual testing of every bug fix and new feature. So it's pretty thorough. However this seems to be one thing that slipped through the net. At this stage I can only apologise for any inconvenience caused.
