If Poser crashes or starts behaving oddly for no apparent reason, it may be that its preference files have been damaged or corrupted.
Removing the damaged files will restore Poser to its factory default settings and may fix problems that won't go away otherwise. This won't remove any additional figures, props or poses that you might have installed.
To remove preferences you must shut down Poser first. You then can Move (Cut and Paste) the prefs files from their location in the folders (as described below) to a New Folder on your Desktop if you wish to back up these file, or you can delete the entire Poser preference folder altogether. If you wish to back up the specific files, then the specific files to back up are:
Poser UI Prefsxxxxx.xml
Poser will rebuild these files the next time you start the program.
NOTE: If you use Multiple Runtimes, the LibraryPref.xml contains your External Runtime Links for your Libraries. You can Copy it back after testing to see if the issue is resolved. If the figure required to check is in an External Runtime, you will need to add that one Runtime back within the Poser application to see if the problem is resolved this way.
Poser 10 and Poser Pro 2014/2014 Game Dev as well as Poser 11/Poser Pro 11 place the Preference Files in the: following locations depending on Operating System
HD > Users > (username) > Library > Application Support > Poser (or Poser Pro) > 10 folder.
Computer\Local Disk C\<username>\AppData\Roaming\Poser (or Poser Pro)\
The UI Preference will be in the English SubFolder.
For Windows if you do not see these folders....
By default, some of these folders are Hidden. To view these Folders, launch Control Panel and select Folder Options.
Select the "View" Tab at the top and place the dot in the "Show hidden files and folders" option and click OK.
