I tried "Add Project to Source Control" for a document. The Desktop interface did nothing, no dialog box appeared. An empty Application-prj folder was created, and a randomly named temp file (MFC5C17.tmp) was placed in the same folder as Application.qvw. I tried again. A new randomly named .tmp file was placed in the folder. I realized that this document had been saved in V10 SR3. When I converted it to a V11 SR1 format document, I was able to commit the document to a new SVN project.
This appears to be a bug to me. If there is a versioning issue, QlikView Desktop should at least give me a warning message telling me to upgrade the application to V11 SR1.
