Unfortunately, running just as unstable as its predecessor

I have ACDSee Pro 6 bought as an update for the version 5, in the hope that it finally is more stable.
Unfortunately, this was a fallacy. It still hangs just like to like with Release 5.
The annoying thing is that the problem usually only occurs when you have a picture just finished editing.
Either the message "ACDSee has caused an error and will be closed" or you get your finished image simply not saved. On the bottom line then sometimes still appears the message: "An internal error occurred".
Really annoying, because this issue taking place since the 4th generation by the program history !!!

ACDSee is actually a good and simple-to-use program with which you can achieve very good results.

Very sorry but due to the problems continue to occur there by me only 2 stars in the hope of an update which now finally irons out these problems.
