No, this isn't the problem, read the whole thread. I have to send
several commands to the server in each method (hundreds of method) and
the method can't continue until the answer has been received. Imagine
a kind of database server:
SQLExecute("select ....") -> call to the server and waiting answer
while SQLMoreRecords
SQLExecute("select ....") -> call to the server and waiting answer
wend.
SQlExecute -> call to the server and waiting answer
SQLSelect -> call to the server and waiting answer
... and so on....
