I2C interrupt with no event flag set

Hi,

A STR912 device is connected via I2C to a pic controller.

The STR912 asks 4 bytes over I2C.

When I use a non interrupt driven communication, it works OK.

When I use interrupt driven communication, after receiving the first 4 bytes, I generate a stop condition. After doing this, I get continuesly an interrupt but no Eventflag is set.

How is this possible ?

If somebody has some idea, plz help me before I become crazy... :-Y
