I created a new text file in VS2010, and added these lines:
Here is a line with one bad wrod. This is line is to test sqell check and such.
Under certain situations, VAX will not detect the misspelled words.
Case 1 - OK Select nothing and run VAX spell check. Result: VAX shows a correction list for 'wrod' and 'sqell' as expected.
Case 2 - OK Select 'wrod' and run VAX spell check. Result: VAX shows a correction list for 'wrod' as expected.
Case 3 - OK Select 'ere is a line with one bad wrod.' and run VAX spell check. Result: 'ere' is skipped since it is a partial word. VAX shows correction list for 'wrod' as expected.
Case 4 - Fail Select 'Here is a line with one bad wrod.' and run VAX spell check. Note 'Here' is now fully selected. Result: VAX reports "Spell check complete". 'wrod' is not detected.
Case 5 - Fail Select all lines and run VAX spell check. Result: VAX reports "Spell check complete". 'wrod' and 'sqell' are not detected.
Case 6 - Fail Place the cursor at the start of 'w' in 'with'. Hold alt + left click and drag a selection box to the end of the second line. Run spell check. Result: VAX reports "Spell check complete". 'wrod' and 'sqell' are not detected. (Should this even work to begin with?)
For case 4 & 5, it seems that the spell checker fails whenever the beginning of a line is selected.
