Gmax questions

Hi everybaddy 
I used FSDS,but I decided to learn Gmax too.I found some tutorials,forums etc...but time-to-time i have questions and don't find answers to it.That's why I started this topic and didn't make separated topics for each question.
Here is 2 for beginning :
1. I made a simple wing,and tried to export to MDL,but an error message pops up :
"The application has run out of memory and will now close."
Exporting worked good before,the error displayed from today.
2. I'd like to see the objects pivot (or axis or gizmo) all the time,but it doesn't appears.
Any idea?
