Max 9.0.5 Issues with [poly~]

Hi all,

Does anyone experience the same issues since Max 9.0.5:

1) I can't always edit a [poly~] patcher. When clicking on Modify Read-Only button in the bottom left corner doesn't work. Also selecting it from the menu doesn't help. When I open the same patcher in Max 8, I don't have this kind of problem. UPDATE: This issue does not pertain to only poly~ patcher, but to any subpatcher.

2) For one active voice, [thispoly~] returns instance index varying between 1-4 - pretty weird. Again, when open in Max8 it just returns 1. When opening all voices one by one, thispoly~ shows them all in a muted state.

3) I also noticed, but that's hard to evidence, more frequent freezes upon save (beachball all day long!) with the same patch. I know, the patch is like 1.5MB, not small and light, but again, in Max8 I think it was much more stable.

I also tried reinstalling yesterday to no avail.

Anyone else?
