Summary: PhotoShop CS2: Photoshop Save As.. dialog ignores filename input on jpegs and names them ".jpg" Product: Wine Version: 1.1.5 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: login@greenstorm.net
1) Open a jpeg image 2) Create a new layer (This forces Photoshop to default to saving as a PSD. You should be able to do anything that can't be saved as a jpeg instead of creating a new layer instead) 3) File-->Save As... 4) Use the pulldown tab to select JPEG. 5) Click the Filename field. 6) Hit Home to unselect ".jpeg" 7) Type a filename 8) Hit enter to save the file.
At this point, Photoshop saves your file with the name ".jpg" (it starts with a ., so it's hidden, but it's there. You'll notice is more the second time you try it in the same folder, and Photoshop asks you if you want to overwrite the file named ".jpg"
Workaround: If you stop at step 7, click the filename field and hit Home again, then hit enter, Photoshop will save your image with the correct filename.
