Page layout shrinks to minimum size
Operating system version
Description of the issue
Developing new file, several tables, several layouts. All was progressing fine. Was working on a layout when suddenly the size became constrained similar to that encountered in label format. Form layouts are white only for the size defined by page layout; beyond that it is grey and fields cannot be dragged to that area.
I have worked extensively with Filemaker 6 PRO and I am trying to re-create programs in the newer format. I have never experienced a problem in 6 that was not easily explained, or corrected - this has me stumped. I am wondering if a Windows 8 incompatibility has corrupted the file.
