* TITLE/SUMMARY [PP] Shrinking height of browser yields premature scroll bar disappearance (broken out of bug #5548) * STEPS TO REPRODUCE 0) Launch Apprunner. View a URL (e.g. www.mozilla.org) 1) Shrink the width of the browser window sufficiently to invoke a horizontal scroll bar. 2) Shrink the height of the browser window so that the page content region comes within 100 pixels or so of the minimum height. 3) Slowly shrink the height of the browser window until you've reached the minimum height. * RESULT - What happened The horizontal scroll bar disappears, roughly when a 60-80 pixels height's worth of page content remains. - What was expected Behavior equivalent to Communicator 4.x; the last of the browser window content should disappear before the scroll bars do. - Occurs On Linux Apprunner (1999102208 build [RH 6.0/GNOME]) - Doesn't Occur On Win32 Apprunner (999102208 build [NT 4, Service Pack 5]) Mac OS Apprunner (1999102211 Mozilla build & 1999102109 Commercial build [Mac OS 8.6]) * CONFIGURATIONS TESTED - [Mac] Beige Power Mac G3 (266 MHz PowerPC 750), 96 MB RAM (VM on; 1 MB of VM used), 1024x768 (Thousands of Colors), Mac OS 8.6 - [Win32] Vectra VL (233 MHz P2), 96 MB RAM, 800x600 (True Color), NT 4.0 SP5. - [Linux] Vectra VL (266 MHz P2), 96 MB RAM. Red Hat Linux 6.0 (GNOME).

[QA Assigning to self to reduce Claudius's enormous bug load.]

Can only reproduce using GFX scrollbars. reassigning to evaughan as p4 for m16

This does not happen when the sidebar is removed. If there is a side bar its because the sidebars splitter's grippy can't shrink past its min size which is the height of the image. This is up to the skin designer to fix. To fix: The vertical splitter (like in the sidebar) should have a min-height of 1px The horizontal splitter (like in mail) should have a min-width of 1px This will allow the window to shrink in height.

This is probably due to a min-width setting on the browser tag in navigator.xul... I'll have a look shortly.
