Help needed with CD - very slow startup after installing v. 1.29

After updating to v. 1.29.0.0 several months ago, I began having more and more problems related to opening the browser. Once opened, it responded quickly, but if closed for a period of time and reopened, it took a very long time. Upon updating two days ago to v. 1.30.0.0, things have only gotten worse. CD works fine once it opens, but start-up times remains VERY long. Has anyone seen this, or can someone offer a possible theory and solution? I love CD!
