To say that the technology sector has been volatile of late is an extreme understatement. It's become a market that has been tough to get in before it runs away from you and tough to get out after it starts to go down. Things don't look like they're going to change anytime soon.

Internet stocks opened mixed today, as traders took profits in some issues and bought into others that were caught in the downdraft earlier in the week.

TheStreet.com Internet Sector

index was down 3.73, or 0.3%, to 1266.93, though it had traded as high as 1278.14.

TheStreet.com New Tech 30 was down 16.97, or 2.1%, to 796.96.

Among stocks in the news,

America Online

(AOL)

was down 1 1/16, or 1.5%, to 70 15/16.

The Wall Street Journal

reported that

Disney

(DIS) - Get Report

has been quietly lobbying

Congress

over fears that its programming would be denied fair access to AOL's Web sites if the online company's merger with

Time Warner

(TWX)

is approved.

Other, more traditional Net names also were lower after rallying sharply the past couple of days.

Yahoo!

(YHOO)

was down 1 13/16, or 1%, to 195 1/4, while

eBay

(EBAY) - Get Report

was off 2 7/8, or 1.2%, to 229 3/4 after it traded to an all-time high yesterday.

Network Solutions

(NSOL)

was off 16 1/16, or 7.5%, to 199 1/2.

PurchasePro.com

(PPRO)

was up 5 31/32, or 5%, to 128 after the company said this morning that results for the current quarter would exceed Street expectations. The

First Call/Thomson Financial

estimate for the quarter is for a 28-cent loss.

The announcement appears to be a response to the hit the stock took after it was listed in the

Barron's

piece this week on companies and burn rates. PurchasePro was singled out in the article, though company CEO Charles Johnson Jr. labeled the report "erroneous," as PurchasePro raised cash in a stock offering last month.

TSC's

Aaron Task

took a closer look at PurchasePro in a

piece yesterday.

B2B plays were mostly higher, as they were among the hardest hit when the market fell apart.

Ariba

(ARBA)

was up 5 1/2, or 2%, to 266 9/16, while

E.piphany

(EPNY)

was up 8 1/4, or 4.6%, to 189 and

Kana Communications

(KANA)

was up 7 11/16, or 8%, to 168 13/16.
