I was changing some timestamps on files and found a bug, where if you have the File: Modified date selected and the File: Created date deselected(empty)..
Change Timestamp changes the File: Created date..

Not suppose to change that field, it was not selected....
Didn't use to do this in older versions...(tested in v0.98.4 .. works like it should)
XnView: MP 0.99.4 - 64 bit - (bug is also in 0.99.1)
OS: Windows 10 - 64bit
