hi tennisball can you confirm it is the same hotfix? 893066 is the id on my latest windows patches.
this would appear then to be a much wider issue than just me - our symptoms are identical, hanging at 16k so I would hazard a guess that this will happen to all users patching this hotfix.
again here is the hotfix info
http://support.microsoft.com/?kbid=893066 - I am guessing the problem is similar to that described on the ms site relating to W2000 but would like FlashFXP support to confirm before I go meddling with regedit.
