Ptle 7 Crashes Options

[straydog]

I have recently upgraded from Panther to Tiger and LE 6.4 to 7.0. Although performance has been significally boosted, Pro Tools often crashes for no obvious reason. There is also some other weird behaviour, like the edit window stopping displaying changes until you re-click on it, or a record-enabled track not recording unless you switch it off and on again. I'm thinking that perhaps some of my plugins need upgrading too, but could it be this that's causing all these problems? Has anybody experienced the same, or does anybody have any ideas of how to solve this? (Lousy digidesign site doesn't seem to mention anything, but in such a chaos I might just have not seen it)

Thanks.
