ZWEI  A must have app!  
(Version 2.7)

ZWEI  Are you using English as your language? ...if you are doing multiple files ...are you dragging them all on at once, or one at a time? Try dragging multiple files onto the app at the same time.

Do any of your files have any weird file names?  
(Version 1.2)

ZWEI  Try downloading the app again. Maybe something got corrupted in the transfer.   
(Version 1.2)

ZWEI  This is how updates should be done!  
(Version 1.5b1)

ZWEI  For those of you using Unsanity haxies, DNS-O-Matic Updater may quit at launch. Put DNS-O-Matic Updater in the global exclusion list in the APE preference pane and it should fix the problem.   
(Version 1.2)

ZWEI  For those of you using Unsanity haxies, OpenDNS Updater may quit at launch. Put OpenDNS Updater in the global exclusion list in the APE preference pane and it should fix the problem.   
(Version 2.2)

ZWEI  If you could zip up one of the files that is unclickable and email it to me I'd like to see if I can figure out what is causing a problem. I can't imagine it being anything on my end, but it's interesting to me regardless.  
(Version 1.2)

ZWEI  How are you creating your .icns files?  
(Version 1.2)

ZWEI  I'm not sure what icon you copied/pasted to your folder, but I can assure you that this app doesn't cause any icon to be unclickable. It can't, actually, because it simply uses a function of OS X to create the icon compatible files. My guess is that you have created an icon with a large percentage of transparency and it's not responding to your clicks because you aren't clicking on a solid part of the icon.   
(Version 1.2)

ZWEI  Thanks for the Leopard update. This app saves me tons of time.   
(Version 1.1)

ZWEI  First thing I download to a freshly installed system. Gotta have it!  
(Version 1.0b51)

ZWEI  Definitely not as polished as Parallels, but it's getting better and the price is unbeatable.

I've only had one problem with it and that was trying to watch a movie via Netflix's "Watch Now" feature. It works under the first beta, but if you install the tools with the second beta it stops working.  
(Version 1.4.1r22965)

ZACH WEIGAND  Works like a charm. Unobtrusive and very useful.  
(Version 1.0)
