Related to 2198 so giving to Chris for a looksee

As of a build on the morning of 1/8/99, I could not reproduce this bug. Resizing worked fine.

This crash appears to have been specific to the low-memory situation that Pierre noted by E-mail. Using the 1/7/98 build, when I expand my screen to ~1200x1000 and resize a page, it works great with a 10 MB partition and 5 MB partition --- but the problems happens with a 1.5 MB partition. So, I'm happy for this to be marked as resolved/fixed as a result of the RAM partition increase since the build at which this was tested.

bumping down severity to major.

marking as fixed because of the RAM partition increase

Verified "fixed" with 1.20.99 build, using a 4.5 MB partition (which is more likely to represent the actual memory availability of the product than the 10 MB default partition that we're currently using.)

Inserting Milestone info.
