There may be several reasons. Perhaps you are using a Java or Flash version of the software, which can lead to slow connections or disconnections. Try downloading the software instead, and playing with that. Your computer may also be low on memory, or your ISP (Internet Service Provider) connection is slow or lagging. Try reconnecting or rebooting your computer. Most problems go away with this. If not, you may have a more serious issue that has nothing to do with playing at an online casino. Contact your ISP or computer maker for more help.
