I now found that the problem is with the directive

{$MODESWITCH NESTEDPROCVARS}.

If I compile the old turbopower_ipro with this directive (even if it 
doesn't need it) it doesn't work (the information box doesn't show 
anything, though I didn't manage to crash lazarus yet), while if I 
rewrite the new iphtml.pas in order to remove the directive it works OK.

A bug in fpc 2.6.4?

Bye
