HTMLViewer position

Once again, I’m modifying the example file for tabbed browser, I’ve got everything worked out except that when I start the app, the htmlviewer won’t align to the left of the tabpanel…until I maximize the window using the window’s controls. After that, shrinking/maximizing the window works perfectly with the htmlviewer resizing/positioning correctly.
In the AddNewTab method, I have tried altering the default:

browser.EmbedWithinPanel(BrowserTabPanel, page, 0, 22, self.Width, BrowserTabPanel.Height -50)


browser.EmbedWithinPanel(BrowserTabPanel, page, 0, 22, 1145, BrowserTabPanel.Height -50)

The reason for this is that with self.Width, the viewer behaves the same, but has no scrollbars. I chose 1145 so the viewer will fit the tabpanel properly and still show scrollbars (odd thing is that 1145 is a bit wider than the tabpanel, but if I size them the same then there’s empty space beside the viewer in the tabpanel).
It bears mentioning that this odd behavior only happens on a linux build. It works fine on windows.
Also, I have the viewer and the tabpanel anchored at left, right, and top.
