Quicker series thumbnail generation when multiple series are located in one folder and the DICOMDIR file is present.
Other performance improvements. Improvements and bug fixes: Sorting mode of studies in the series preview bar can be changed to "newest first" via options.xml file.
Fixed: cine loops exported to WMV files had sometimes incorrect frame rate.
