Can’t find anything about this on the forum: has anyone run into problems with serial ports, select call, critical enter or critical exit between Max 5.0.5 and Max 5.0.7? We have runtime versions that were compiled on 5.0.5 and 5.0.6 and they run on 5.0.5, 5.0.6 and 5.0.7. However the actual Max/MSP code crashes on 5.0.7.
