I have just configured a stack of 2 Cisco 3750 switches, and everything works fine
Switch/Stack Mac Address : 001c.577d.7b80
H/W Current
Switch# Role Mac Address Priority Version State
----------------------------------------------------------
*1 Master 001c.577d.7b80 2 0 Ready
2 Member 001f.9d79.5d80 1 0 Ready
The only consern is that two switches have different IOS
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 12 WS-C3750G-12S 12.2(35)SE2 C3750-ADVIPSERVICESK
2 12 WS-C3750G-12S 12.2(35)SE5 C3750-IPBASE-M
As far as I know all the switches in the stack need to have the same IOS version. How is this possible then in my case that 2 switches with different IOS formed a stack with no problems?
Thank you!

The legacy 3750 allowed to have different versions (up to a certain degree) and even different feature-sets. That allowed you to have for example a stack of eight switches, but only two of them run the more expensive IP-Services image while the others only have the base image. In scenarios like this you have to make sure that the stack-master is always a switch running the highest feature-set.
More informatio on that topic is in the documentation:

Try turning OFF switch 1 and see if your configuration works.
