Drag & drop multiple files doesn't work correctly, i.e. WinMerge. I often will select multiple files and drag them onto WinMerge to compare the two files. Appetizer opens multiple instances of WinMerge for each file. Not cool.
Desired behavior: launch winmerge.exe %1 %2
Current behavior: launch winmerge.exe %1 and winmerge.exe %2
Please change!!

This ought to be a simple fix... where can I submit this as a bug report?
