strange STP behaviour : stack port in "sh spanning-tree" output

Hi All

I have three 3750 switch connected in stack ...

Issuing "sh spanning-tree root port" only for VLAN 242 and 243 you can see stack port 1 as root port ....

This is quite stange ....

Have you ever happened something like this???

All works well but I cannot understand if this behaviour is correct...

regards

Giuseppe

p.s. in attach two useful output...
