To Antonio: Problem with multi select xBrowse

[HunterEC]

Guys:

When using a multi select xBrowse if the end user presses Ctrl-Page Down or Page Down all previous selected records becomes unselected. Any ideas what's wrong ? Here are the steps:
1. User selects a couple of records, they stay highlighted.
2. User press Ctrl-Page Down or Page Down.
3. All previous selections become unselected.
Thank you.
