Here is a list of all changes from v2.10:
New features:
New menu option "File->Next/Previous->Wrap" that lets you select if PMView's File Sequencer should wrap at the last/first file or not.
New menu option "View->Show->Window Borders" that lets you hide the window borders of PMView's main window.
The following bugs and problems are fixed:
Screen capture: Problem with using the keyboard mnemonics {Alt-F}{T}{S} to activate File->Capture->Screen for hot-key capture [OS/2 only]
Pressing ALT twice in the main window causes the status bar to go blank [Windows only].
File Open/Save dialogs: It is not possible to rename or delete folders. The menu entries for these functions are grayed out. [Windows 2000 only].
The "Copy" and "Preserve Color Depth" menu items in the "Edit" menu use the same mnemonic character.
PMView does not ask for save confirmation if the File Save dialog is open.
Dragging files and dropping them back in the source folder gives an error message [Windows only].
The folder list in the File Open/Save dialog does not auto scroll during drag&drop [Windows only].
Convert to Black&White: Conversion of a Deep Color image results in an image that PMView internally still thinks is Deep Color. Saving this file results
in a Deep Color image instead of a Black&White 1-bit image.
File Open dialog: File open dialog opens with no files.
General: Fixed a problem with entering the decimal separator in entry fields.
General: Some files cause PMView to crash.
About dialog: The About dialog does not display the version number of PMView.
