To elaborate on the topic:
Does someone know how it works with "arrange horizontally" or "arrange vertically".
I use version MC 9.0 and I never could get above to arrange my charts the way I want.
The charts are vertically arranged next to each other. So I can not use "arrange all".
For example, every new startup of MC, the size of the charts are a bit off. But there are still in the right order. I usually adjust the size manually so the charts touch each other again. With the above option it will change the order of the charts everytime.
I'm not sure that I've fully understood the problem you're having but my observations are:
1. As far as I can tell, unlike 'arrange all', the chart order of 'arrange vertically' and 'arrange horizontally' is determined by the order in which the charts were first added.
2. The order doesn't change. Even if you first click the charts in random order and select arrange all (or manually move them around and/or manually resize them etc.) - selecting arrange vertically/horizontally afterwards will still restore the charts in their original order.
3. I'm using MC 9.1 and restarts of MC do not result in the charts being 'a bit off'.
4. If that is only happening in MC 9.0, then you could try what is described in '1' above (i.e. clicking on 'arrange all' and then 'arrange vertically' should restore the charts in their original order, size and alignment. Then they should no longer be 'a bit off' - without you having to manually adjust their sizes so that they touch each other. That's what happens in MC 9.1 x64
