Errors im Mathematica??

I worked with Mathematica very intensively, lately, and encountered 
several - partly strange - problems:
1) In functions Mathematica somtetimes tries to multiply statements with 
each other, which follow one after the other in different lines. This 
seems especially the case with Print statements. The problem disappears, 
if I put ";" behind the statements. I think, this is a consequence of 
the fact, that the multiplication sign may be omitted.
2) Error messages have no newline behind them, therefore the following 
output of the program is appended to the end of the error message on the 
same line.
3) Using the "ToExpression" statement I often get the error message, 
that the argument is not a string, although it is a string.
Mathematica seems to replace parts the argument by similar statements in 
the program, before it makes the source to a part of the program. In one 
case, I tried to remove the statement in the program and got the error 
message:
The text replaced was not a string.
