Lines: 25 I was doing a simple experiment in Hypercard and came upon the following problem... Hypercard is doing disk I/O at inopportune moments. Specifically, when a script writes to a field (eg by use of a put command), hypercard will do some disk I/O. This disk I/O tends to screw up the mouse button handling, even to the degree of missing clicks. I thought it might be due to hypercard calling in special fonts, but it happens even with the default font/size/style. My suspicion at this time is that hypercard is updating stack information. I have tried different size ram caches to no avail. I have set userlevel to 2, which appears to reduce the frequency of I/O but not nearly enough. On the other hand, manual typing into a field does not generate these disk operations. (also, using the hypertalk TYPE command doesn't cause the disk operation but it does cause me other problems..) It would be a big help if someone could give me a more exact explanation as to what is happening or an idea on how to convince hypercard to defer the disk I/O???
