"Exclude enzymes found in the exclude region" incorrect behaviour

Scenario 1:

1. Open "clipboard_2.seq"(see attachments).
2. Open "Restriction enzymes"dialog.
3. Choose only one "AasI" enzyme.
4. Check "Uncut area" and set it from 29 to 100.
5. Click OK.
   Current: an enzyme on 28-39 was found.
   Expected: no enzymes were found.

Enzyme should be found only if it doesn't intersect the "uncut area".

Scenario 2:

1. Open "clipboard_3.fa"(see attachments).
2. Open "Restriction enzymes"dialog.
3. Choose only one "AasI" enzyme.
4. Check "Uncut area" and set it from 50 to 100.
5. Click OK.
   Expected: no enzymes were found, because the "AasI" enzyme exists inside of the "Uncut area".
6. Open the log window.
   Expected: there is a sign on the algorithm->info level "The following enzymes were found, but skipped because they are presented inside of the "Uncut area": Aasi."
   Also, please, don't forget to translate this sign to Russian. 

Scenario 3:

1. Open any sequence, Restriction sites dialog.
2. Set Region 5-10, check "Uncut region"and set in "1-20".
3. Click "OK".
   Currect: Calculation run, nothing found.
   Expected: the "Uncut region"was highlighted in red, the "OK" button of the RS dialog is disabled.
