Disappearing INPUTS Tab

 
I am working on a rather large EA. The .ex4 is about 38K and it references 7 libraries (.mqh files). I have now lost the INPUTS tab when I attach the EA to a chart. The COMMONS tab appears but no INPUTS tab. Same problem when I look at the EA properties once it is attached to a chart and the same is true in Strategy Tester. Other (smaller) EAs work fine. The EA is recompiling and attaching with new compiled values for the EXTERNs just fine. I just can not access the input parameters once the EA is attached.

The location of my MetaTrader 4 system involves a rather long file reference: "Documents and Settings/All Users/Documents/Shared Trading/Interbank/Experts" would be the beginning of every file reference involved with excuting the EA.

Any suggestions for a workaround?  I have reduced the the length of some folder names and the .mqh file names, but nothing helps.
