Camstudio v2.6, release 273:

------------------------------
Fixed a memoryleak that caused Camstudio crashed after 40-50 minutes of recording.
Redesigned the region calculation routines.
* The same procedure is now applicable for all sizing calculations.
* The area you define in regions is the area that will be recorded. No shift in position or losing rows or columns.
* Size of the region is now displayed correctly in the progress monitoring window.
* Size of the recording is now equal to the size as displayed the progress monitoring window.
