Form extremely slow when adding formula line

Hey guys.

My problem is quite objective. Any form that I add a formula line to opens is very slow, removing this line opens quickly. I have already tried the following actions:

• Restart the environment
• Refresh
• Create a new one
• Reduce number of lines
• Select members at level 0 (non dynamic)
• Using SmartView we have the same problem
• Using Form 1.0 or 2.0 the same thing happens.

Even reducing the number of members that will be displayed, the problem occurs. So it's not a problem related to the data that will be displayed, because when I remove the formula line it opens very quickly.
