Upgraded to 2010b - can no longer specify Fixed-Step ODE4 with continuous states

Have had the following solver specs for years - worked great:
1) Type: Fixed-step 2) Solver: OD4 (Runge-Kutta) 3) All of our models have continuous states
I am trying to use embedded encoder with target support package (Spent big bucks for all these painful toys) on 2010b using idelink_ert.tlc.
No choice at all is now available for a solver - just a series of endless catch-22s. Can't use fixed setup with OD4. Can't pick OD4 with variable-set. Can't use descrete because all our models are full of continuous signals.
This is mind numbing, What have you done with Simulink?

Can you provide the error message you are receiving when trying to use ODE4? Is it during simulation or during code generation?

In fact, in Solver selection tab, Solver Type: Fixed-Step is selected, then all of the solvers ode1 (Euler), ode2 (Heun), ode3 (Bogacki-Shampine), odeFixed-step4(Rungge-Kutta), etc., are all fixed step solvers. By default, Fixed-step size (Fundamental sample timee) is "auto" that can be altered with a user entry.
