CPU Utilization ? Very High Very Little Activity

P: n/a
Hello:
Use C# 2003 .Net Frameworks 1.1 SP1, OleDbConnection
I open an Access data using a class (dataset has many pictures in it) and
scroll back an forth using the four arrow keys. Recs displayed on screen, a
short
time after CPU utilization moves up(according to Taskmgr), it stays at the
new rate for a while, you scroll more it moves up more and stays a new higher
value, after a few minutes of scrolling it will peg at 99%. Even if pictures
are not displayed but just text info this still happens. The program has
whatever
the default threading is for C#(I do not define any threads).

What could cause this ?

How much memory does your machine have? How much virtual memory?
Check in the task manager what task is consuming the CPU.

The task I have written in C# is consuming the CPU, the machine has 1G Ram/
Windows XP. Somehow the more you hold down the scroll arrows the more cpu
is uses but never releases the Cpu usage.
