I've had this problem show up sporadically for some time, but now I can't get rid of it.
I have an NSOutlineView with several columns, two of which have checkbox behaviour. In these columns I set a NSButtonCell in IB having the checkbox behaviour, and in fact I want to have custom images rather than the standard checkbox, but since the bug shows up with the standard checkbox I'll leave it at that.
In IB, all appears fine:

But when I load and run the nib, all is not fine - the checkboxes are replaced by some very ugly buttons:

In the past when this occurred, I found that if I triggered a need to save in IB by performing some dummy edit, and resaved the nib, it would often be enough to correct the issue. Sometimes it took a couple of tries. However, now it seems permanently broken. This resaving trick might indicate a bug with writing out these cells in IB, or perhaps with parsing the xib to make the nib, who knows.
However, I also tried forcing a bunch of settings on the cells in code after they are loaded in -awakeFromNib, and that doesn't seem to help either.
I'm really stuck now. Can anyone suggest a way to fix this, or anything to try?
