Is the ActiveX-control you obviously embed written with Delphi?

No.
One time i get the same error with no use any active X So i suppose that my
bug isn't linked ith the activeX

The bug is induced by another application that doesn't restore
the floating point status registers of the coprocessor.
Code written with Delphi tend to have this bug.

It must be an application that installs hooks in every
process. Try to stop everything that you don't need
on the machine, like virus scanners, window managers, etc.
