Problem to launch an application, except in Safe mode.

[Guest Daniel]

Hi everybody.

 

I have this application (a French dictionnary) which worked beautifully for

years, until this morning. It is a "one-session only" app.

 

Now, for some reason, when I launch it, nothing happens. If I try to launch

it again, I get a *normal* message (i.e. generated by the application)

indicating that this application is already being used.

 

However, it doesn't appear in Task Manager / Application.

 

I cannot relate this problem to anything I could have done. My system (DELL,

Windows XP SP1) is very stable, maintained, and I didn't install any

program lately. No virus, as far as Norton can say. No other bug I know of.

 

I tried to reinstall the application, after cleaning the registry, to no

avail.

 

Important : this program works perfectly OK in Safe mode !

 

Where should I look, investigate ? Anything special I couls check ?

 

Many thanks in advance for your kind help.

 

with best regards,

Daniel
