Columns In FixedHeader Section Grow Taller During Scrolling - Why?

Greetings,

I have a wide report. The leftmost two columns have the FixedHeader property set true so they remain visible when I do horizontal scrolling. My problem is that the height of the 1st two rows in the fixed header section increases as soon as I scroll the report to the right. The height of the 1st two rows in the fixed header section roughly doubles while the height of the scrollable section remains the same. The upshot is that the fixed part of the report is misaligned with the scrollable part (because the rows in the two sections don't have the same height). Only the 1st two rows in the fixed header grow taller - the other rows in the fixed header retain their original height.

Has anyone seen this problem or have an idea what is happening?


Thanks,
BCB

This is the style that is generated for one of the fixed header columns:

.a6
{overflow:hidden;
HEIGHT:100%;
WIDTH:100%;
font-style:Normal;
font-family:Verdana;
font-size:8pt;
font-weight:Normal;
text-decoration:None;
direction:LTR;
unicode-bidi:Normal;
text-align:left;
writing-mode:lr-tb;
vertical-align:Top;
color:Black;
word-wrap:break-word
}
