This has the same issue I reported.
The text is clipped,
If I don't let the updater touch the files from the original zip, I don't get this problem.
The updater only touched some of the zone files and not the scrollpage.xml.
But here is what I found is going on.
<page Name="exp04_rgn_jarsath_wastes_1" OnShow="
parent.ScrollPageExtent.Size=Size parent.ScrollExtent=Size parent.MinimumScrollExtent=Size" PackSize="a,f" PackSizeProp="-010/0001,0002/0003"
ScrollExtent="255,3080" Size="255,3080" Visible="false">
In the above code from a zone file, it overwrites the scrollpage info which has been orginally set in Scrollpage.xml to
<Page Location="7,30"
MinimumScrollExtent="487,1122" Name="ScrollPage" PackSize="a,a"
ScrollExtent="487,1122" ScrollLocation="0,687" ScrollSize="30,30" Size="235,435">
Also interesting is that the PackSize width of the zone files is set to Absolute. So OnShow it adjusts the size of the parent and then it is affected by the resize further crunching the window. If I understand this correctly, it explains the windows viewable area being compressed by the difference of 232 after the ScrollPageExtent is adjusted to 255. Leaving a new ScrollExtent on the zone file of 23. The picture above seems to suggest that is what is happening.
I think if the files didn't adjust the width of ScrollPageExtent and ScrollExtent the problem would go away. I can understand adjusting the height based on data content, but the width should be constant since it has a fixed element width for the data anyway.
Also noteworthy:
Restoring the zone files (pre-update) corrects some of the cutoff, but using this updated eq2ui_custom_poifinder.xml the text rolls off the edge of the page and still has some cutoff on the right before the scrollbars.
