I really used to be fond of photostack. I have not used it for some time and recently considered bringing all my photos together in a windows 11 pc. using it However it seems that it does not exit or shut down as expected. Consequently it is only possible to close the program using windows taskmaster. Otherwise it lurks using 25% cpu although it doesn't show on screen that it is still running. Because it is still 'running' clicking the photostack icon in the photoplus task bar or in the menu list has no effect! I do not feel able to use this feature until I can resolve this problem. Can any one help or comment on similar experiences
