proteus timestep too small

Hi all

My problem is connected with Spice I believe. Why I cannot simulate switching capacitors. I have the simplest design with one capacitor which is chared trough one switch and then when cpacitor is charged it discharges its capacity trough resistor. This situation is almost impossible to simulate(time step too small). In user manual there was mentioned when switching capacitors such problems may occur. But what is the solution to the problem. Maiking initial states ?
Please help.

With regards,

MK
