FM's limit to number of search and replace operations query

[Rob Shell]

Hi Framers:

I am in the final stages of a manuscript and trying to resolve matters like 
spaces after colons and punctuation. I thought I knew all the tricks, but 
when I do the Search and Replace with more than 3,500 operations in one 
file, FM crashes. I would not have thought FM would have limits (thought in 
fact it looped until it had done everything)  so I am blaming myself. Small 
1 to 3499 opeartions go well.

running XP and FM7.2 with updates.
