Shareaza

I saw that Ticket # 182 is closed because it can't be reproduced.
When you start Shareaza and (after connenting) start a search you will have plenty ED2K results.
When you start the same search when Shareaza is running for 10-15 minutes you will have not one ED2K results at all.

ED2K forbid too often searches otherwise you will be banned. By default file queries limited to one per hour. Shareaza has no KAD support yet so has no access to fast re-queries.
