Nope, you do have to edit the xml. It doesn't bite. =)
Copy the EQUI_BazaarSearchWindow.xml file from the default folder into your custom one... and open it in notepad. Find this section:
<Listbox item = "BZR_ItemList">
<ScreenID>BZR_ItemList</ScreenID>
<DrawTemplate>WDT_Inner</DrawTemplate>
<TooltipReference>Right click item name to inspect item. Right click player name to face player.</TooltipReference>
<AutoStretch>true</AutoStretch>
<LeftAnchorOffset>5</LeftAnchorOffset>
<TopAnchorOffset>80</TopAnchorOffset>
<RightAnchorOffset>5</RightAnchorOffset>
<BottomAnchorOffset>2</BottomAnchorOffset>
<TopAnchorToTop>true</TopAnchorToTop>
<BottomAnchorToTop>false</BottomAnchorToTop>
<LeftAnchorToLeft>true</LeftAnchorToLeft>
<RightAnchorToLeft>false</RightAnchorToLeft>
It should be very near the top of the file. Go to the line I put in pink, and change it to look like this:
<!--<TooltipReference>Right click item name to inspect item. Right click player name to face player.</TooltipReference>
-->
you just have to add the beginning and end symbols (the ones shown in pink) and save the file.
Or, ask one of us nice folks to do it for you.
