Drop out when minimizing to tray

[Geostranger]

Hi & hello to everyone,,
I'm a new user of this forum & I'm looking for some help.
My system runs XP-home, connected by adsl2 & using Limewire 5.5.9 after a recent upgrade.

Seems everytime I run Limewire it requires a restart from the programs list, especially after the screen saver has activated.
i.e.
Each time I start the program allowing it to run then "minimize to tray".
Allowing the computer to activated the screen saver, I then re-activate the screen & attempt to access it from the icon tray, only to have the icon disappear completely.

Requiring a restart from the programs list.
I've tried to see if there is a option I can disable or function I can change but with no luck.

Has anyone else suffered this?
If so what can I do?
