The last available version of Dadaware Embellish had a problem with keyboard shortcuts: the various keys combinations were captured and acted upon even if Embellish was not the active application. For example trying to copy/ paste files in Windows Explorer using the keyboard Ctrl+C/ Ctrl+V while Embellish was running (but in the background) ended in a a copy/ paste operation in Embellish. This is very annoying because these operations are not carried (in the foreground application) as intended, and also can inadvertently damage to the work in progress in Embellish. The bug manifests itself even on old Windows versions (Win95), it is not specific to newer ones.
Judging on the behavior, I guess these shortcuts were implemented using a system-wide keyboard hook; better is to implement them with accelerators (ACCELERATORS resources/ TranslateAccelerator() WINAPI).
